57.2 is what percent of 313 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 313 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 313, so we can write it down as 100%=313.
4. We know, that x% equals 57.2 of the output value, so we can write it down as x%=57.2.
5. Now we have two simple equations:
1) 100%=313
2) x%=57.2
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=313/57.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57.2 is what percent of 313

100%/x%=313/57.2
(100/x)*x=(313/57.2)*x       - we multiply both sides of the equation by x
100=5.472027972028*x       - we divide both sides of the equation by (5.472027972028) to get x
100/5.472027972028=x
18.274760383387=x
x=18.274760383387

now we have:
57.2 is 18.274760383387% of 313
